| Looks like we may get a treat  i have been preaching about this stuff in EW presentations for ages now and i hope we invest in this stuff.

The water cannon is old hat these days when you consider that the Home Office is currently evaluating sci-fi raygun technology from the US as a crowd control measure. The high-tech pain rays - or Active Denial System - from Raytheon is a truck-based system that can fire blasts of radiation from up to half a mile away and which induces an all-over sensation of burning. Lovely.
The 100,000Watt beam penetrates the very top layer of the skin making those protesting rush backwards away from the burning-like pain. Outside of the beam, the pain disappears. There's even a backpack version on test.
"Directed energy systems such as the ADS have seen major advances over the past few years and are likely to continue to do so in the coming years," the Home Office told The Times.
Despite admitting that they found "no options that would currently be considered" it added that may change in the future
"We're not saying that the ADS is never going to be used. We're not going to write it off."
Despite medical tests on volunteers saying the tech is not very harmful, but very effective, the public has been much less enthusiastic. So much so that it still hasn't been rolled out by the US Defence Forces.

| Quote: | The ADS works by directing electromagnetic radiation, specifically, high-frequency microwave radiation, at a frequency of 95 GHz[6] (a wavelength of 3.2 mm) toward the subjects. The waves excite water molecules in the epidermis to around 130 °F (55 °C), causing an intensely painful sensation of extreme heat. While not actually burning the skin, the burning sensation is similar to that of a light bulb being pressed against the skin.[6] The focused beam can be directed at targets at a range of just under half a kilometer, or about 550 yards.[7] The device can penetrate thick clothing, although not walls.[7]
At 95 GHz, the frequency is much higher than the 2.45 GHz of a microwave oven. This frequency was chosen because, due to the stronger absorption of water at those frequencies, they penetrate the skin to a depth of less than 1/64 of an inch (0.4 mm),"[8] which is where the nerve endings are located.
A spokesman for the Air Force Research Laboratory described his experience as a test subject for the system:
"For the first millisecond, it just felt like the skin was warming up. Then it got warmer and warmer and you felt like it was on fire.... As soon as you're away from that beam your skin returns to normal and there is no pain."
Electromagnetic radiation cannot pass through a conductor, so the effect can be shielded by a a conductive mesh or foil which forms a Faraday cage around the target.

| the police had some sort of this it was on Utube high frequency making people run away it`s cool
